You cannot change to the otheroperation mode.⋅ When a frequency is input from the external signal bymulti-speed setting, it has a higher priority than thefrequency setting of the PU. When AU is on, thecommand signal to terminal 4 is used.(7) PU/external combined operation mode 2 (setting "4")3 4 5 6 78910Hz⋅ Select the PU/external combined operation mode 2when applying frequency command from the externalpotentiometer, multi-speed or JOG signal and inputtingthe start command by key operation of the operationpanel (FR-DU07) or parameter unit (FR-PU04/FR-PU07).⋅ Select "4" for Pr. 79.

Selection of operation mode and operation location(8) Switch-over mode (setting "6")⋅ While continuing operation, you can switch between the PU operation, external operation and network operation(when RS-485 terminals or communication option is used).Operation Mode SwitchingExternal operation → PUoperationExternal operation → NEToperationPU operation → externaloperationPU operation → NEToperationNET operation → externaloperationNET operation → PUoperationSwitching Operation/Operating StatusSelect the PU operation mode with the operation panel or parameter unit.⋅ Rotation direction is the same as that of external operation.⋅ The frequency set with the potentiometer (frequency setting command), etc. is used unchanged.(Note that the setting will disappear when power is switched off or the inverter is reset.)Send the mode change command to network operation mode through communication.⋅ Rotation direction is the same as that of external operation.⋅ The value set with the setting potentiometer (frequency setting command) or like is used unchanged.(Note that the setting will disappear when power is switched off or the inverter is reset.)Press the external operation key of the operation panel, parameter unit.⋅ The rotation direction is determined by the input signal of the external operation.⋅ The set frequency is determined by the external frequency command signal.Send the mode change command to network operation mode through communication.⋅ Rotation direction and set frequency are the same as those of PU operation.Command to change to external mode is transmitted by communication.⋅ Rotation direction is determined by the external operation input signal.⋅ The set frequency is determined by the external frequency command signal.Select the PU operation mode with the operation panel or parameter unit.⋅ The rotation direction and frequency command in network operation mode are used unchanged.(9) PU operation interlock (setting "7")⋅ The PU operation interlock function is designed to forcibly change the operation mode to external operation mode when thePU operation interlock signal (X12) input turns off. This function prevents the inverter from being inoperative by theexternal command if the mode is accidentally left unswitched from PU operation mode.⋅ Set "7" (PU operation interlock) in Pr. 79.⋅ For the terminal used for X12 signal (PU operation interlock signal) input, set "12" in any of Pr. 178 to Pr. 189 (inputterminal function selection) to assign the function. (Refer to page 206 for Pr. 178 to Pr. 189.)⋅ When the X12 signal has not been assigned, the function of the MRS signal switches from MRS (output stop) to thePU operation interlock signal.X12 (MRS)Function/OperationSignalOperation modeParameter writeOperation mode (external, PU, NET) switching Parameter write enabled (Pr. 77 Parameter writeON enabledselection, depending on the corresponding parameterOutput stop during external operationwrite condition (Refer to page 55 for the parameter list))Forcibly switched to external operation modeOFF External operation allowedParameter write disabled with exception of Pr. 79Switching to PU or NET operation mode disabledOperating ConditionOperationStatusmodePU/NETX12 (MRS)SignalOperationModeOperating StatusSwitching toPU, NETOperation ModeDisallowedDuring stop ON→OFF *1If external operation frequency setting and start signalExternal *2Running ON→OFF are entered, operation is performed in that status.*1 DisallowedOFF→ONAllowedDuring stopDuring stopON→OFFDisallowedExternalExternal *2OFF→ON During operation → output stop DisallowedRunningON→OFF Output stop → operation Disallowed*1 The operation mode switches to external operation mode independently of whether the start signal (STF, STR) is on or off. Therefore, themotor is run in external operation mode when the X12 (MRS) signal is turned off with either of STF and STR on.*2 At alarm occurrence, pressing of the operation panel resets the inverter.CAUTION⋅ If the X12 (MRS) signal is on, the operation mode cannot be switched to PU operation mode when the start signal (STF, STR) is on.⋅ When the MRS signal is used as the PU interlock signal, the MRS signal serves as the normal MRS function (output stop) byturning on the MRS signal and then changing the Pr. 79 value to other than "7" in the PU operation mode. Also as soon as "7"is set in Pr. 79, the signal acts as the PU interlock signal.⋅ When the MRS signal is used as the PU operation interlock signal, the logic of the signal is as set in Pr. 17. When Pr. 17 = "2",read ON as OFF and OFF as ON in the above explanation.⋅ Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Pleasemake setting after confirming the function of each terminal.288
